Explanation / Answer

B)

(i) 20 ml of 1.00 M LiCl

1.00 M LiCl = 1 mol/L

20 ml = 0.02 L

Number of moles of LiCl present = 0.02 L * 1 mol/L = 0.02 mol

(ii) 10 g of 12.15 (%) mass LiCl

We have 12.15 g LiCl for every 100 g of solution

So 10 g of solution contains 1.215 g LiCl

Mol weight of LiCl = 42.39 g

Number of moles of LiCl present = 1.215 / 42.39 = 0.0286 mol
